摘要
本文采用分光光度法分析CIBA—GEIGY公司的三原色染料之光谱特性,以及相互配合成不同颜色的光谱吸收特性.结果表明这些染料颜色纯度高、副色少,配合染料亦呈现较理想的吸收光谱,且为其原色染料的吸收值的加和.通过对皮革的染色试验证实这三种三原色染料具有非常相似的渗透率和上染率.
The spectral absorption characteristics of chromogenic dyes and brown dye, provided by CI-BA-GEIGY corp. were analysed by spectrophotometric methods, and the mixed dyes were also analysed. It is showed that these dyes have higlvpureness of the colour and little by-colour, and mixd dyes have ideal absorption spectra which have additive property. It was confirmed by dyeing test of leather that three chromogenic dyes have similar permeability and dye-absorption in leather.
